6 Claims, 3 Drawing Figures HAND VISE FIELD OF INVENTION The present invention relates to vises, and more particularly to vises having static jaws which are operable to develop suitable compressive force to support and retain piecework.

DESCRIPTION OF THE PRIOR ART Vises commonly used and employed usually consist of a pair of jaws which can be brought together by means of a screw, toggle, or lever, used for holding work that is to be operated on. It has been found that opening, closing, tightening, and loosening a vise about a workpiece may require considerable agility and skill because the operator usually is handling the workpiece while simultaneously operating the vise. Various sorts of quick-releases, toggles, and other hinged locking means have been offered to permit the operator to swing one of the jaws over the workpiece into engagement with the opposite jaw assembly. These only reduce a portion of the work and agility required to operate the vise, and may include complex and sometimes delicate mechanisms and assemblies.

Accordingly, it is an object of the present invention to provide a vice having static jaws which are operable to develop suitable compressive force to support and retain aworkpiece.

A further object of this invention is to provide the vice having static jaws with a suitable frictional laminate to inhibit release of the workpiece from the jaws.

It is another object of this invention to provide the vice having static jaws with a suitable frictional laminate having a suitable resilient cerated surface to inhibit release of the workpiece from the jaws.

These and other objects shall become apparent from the description following, it being understood that modifications may be made without affecting the teachings of the invention here set out.

SUMMARY OF THE INVENTION The hand vise comprises a substantially M-shaped framework, mounting leaves fastened to the outer leg portions, and 'a frictional laminate disposed over the upper portions of the framework. An object is locked into the vise by tension of the outwardly inclined jaw portions and by the frictional laminate.

A more thorough and comprehensive understanding may be had from the detailed description of preferred embodiment when read in connection with the drawings forming a part of this specification.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the hand vise of this invention including a sawhorse on which it is mounted, and a cylindrical workpiece both shown in broken lines for illustrative purposes.

FIG. 2 is a perspective view of the apparatus of the FIG. 1 drawn to a larger scale.

FIG. 3 is a perspective view of a further embodiment of the hand vise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and more particularly to the FIG. 1, the hand vise of this invention is shown to advantage and generally identified by the numeral 10. The hand vise 10 may be mounted on any of a number of support structures such as a common sawhorse 11. The vise 10 is operable to support and retain any of a number of workpiece objects such as a cylindrical workpiece l2. 2

Referring to the FIG. 2, the hand vise 10 comprises a framework 13, mounting leaves 14, and a frictional laminate 15. The framework 13 is an upstanding, substantially M-shaped structure having a pair of leg portions 16 and 16' which are inclined centrally from their respective lowermost terminal ends. The framework 13 also includes a pair of jaw portions 17 and 17' which are fastened to the uppermost terminal ends of the legs 16 and 16', which are inclined centrally from their respective uppermost terminal ends and which are fastened to each other at their lowermost terminal ends. It may be seen that the jaws l7 and 17' are operable to form a saddlelike region in which the workpiece 12 may be carried. The intersects of the portions 16 and 17, 16 and 17', and 17 and 17' may be spaced apart by web members 18, 18' and 18". It has been found that the capacity of the size of the cylinder 12 may be predeterminately modified by varying the interior angle of the jaws l7 and 17', and by varying the length of the web member 18". The framework 13 is fastened to the sawhorse 11 by mounting leaves 14 which are dependently disposed in a horizontal juxtaposition from the lowermost terminal ends of the leg portion 16 and 16'. Each of the mounting leaves 14 includes fastener receiving holes 19 as do web members 18 and 18 It is to be understood that the framework 13 may be fabricated of a single meta] strip havingsuitable brakes forming the M-shaped structure with its respective portions 16 and 16' and 17 and 17', or from separate, suitably fastened sections.

The frictional laminate 15 is intended to resist torque on, and retain the workpiece 12 in, the jaws 17 and 17. The frictional laminate 15 is provided over the upper surfaces of the framework 13 and particularly in the upper surfaces of the jaws 17 and 17' and the web member 18". The frictional laminate 15 may be constructed of a resilient, high-adhesion elastomer. The elastomer material for the laminate 15 may include such materials as rubber, neoprene, polypropylene and the like. It may be seen that the object 12 will tend to be retained in the jaws l7 and 17 by the sticky, frictional characteristic of the laminate l5 and, thus, will not rotate between the jaws l7 and 17' and the tension of the jaws l7 and 17' on the cylinder 12 will not tend to eject the workpiece 12. It may also be seen that as downward force, or force applied to the cylinder 12 during work will further force the cylinder 12 downwardly between the jaws l7 and 17' tending to cause the frictional laminate 15 to further cohere about the cylinder 12.

As shown in the FIG. 3, a further embodiment of the hand vise 10 includes a framework 13' having mounting leaves 14' and including mounting fastener holes 19', which is substantially identical to the framework 13 and 14. The vise 10 also includes a frictional laminate 20. The frictional laminate 20 may also be fabricated of an elastimer or other resilient material and is configured in a multiplicity of serrations 21. The serrations are operable to gather about a cylinder 12 to retain and embed the cylinder 12 in the vise 10. It has been found to advantage to configure the serrations 21 in a downwardly disposed tooth-like configuration to permit easy insertion of the cylinder 12 while inhibiting withdrawal of a cylinder 12 from between the jaws 17 and 17.

As shown in the FIG. 1, the cylinder 12 is placed in the satellite region formed by the jaws 17 and 17. The cylinder may be locked into the vise by downward force applied on the cylinder 12. The cylinder 12 is retained by tension of the walls 17 and 17', and by the effects of the frictional laminate 15 set out above. Thus, it may be seen that advantage may be had in a hand vise 10 which has the walls 17 and 17 fabricated of a semielastic, high tensile strength material which may readily conform about the cylinder 12. The cylinder 12 may be withdrawn from the vise 10 by merely lifting the cylinder 12 with sufficient force to overcome the compressive forces developed by the jaws 17 and 17 and the laminate 15.

Having thus described in detail a preferred apparatus which embodies the concepts and principles of the invention and which accomplishes the various objects, purposes and aims thereof, it is to be appreciated and will be apparent to those'skilledin the art that many physical changes could be made in the apparatus without altering the inventive concepts and principles embodied therein. Hence, it is intended that the scope of the invention be limited only to the extent indicated in the appended claims.
